Alzheimers Drug Turns Back the Clock in Mitochondria

"An experimental drug J147 reverses some symptoms of Alzheimer" but "researchers had to resolve the mystery of how it works". Is this the way how modern medicine has to work???

Dr Dale Bredesen, a scientist who developed a program to reverse all symptoms of Alzeheimer and cures 9 out of 10 patients with early Alzheimer knows exactly what causes Alzheimer. He knows so much about Alzheimer that he identified 3 subtypes. His treatment focuses on 36 points since there are many factors that contribute to Alzheimer. He refers to Alzheimer as a roof with 36 holes and the necessity to plug all holes to stop having rain inside the house.
